When you select an exercise on your watch - snowboarding, after synchronization with Garmin Connect, these exercises are recorded in the application as - Ski.

On my watch (FR945) I got the activities "Ski" and "Snowboard". In Garmin Connect there are no corresponding activities. Instead they are both logged as "Resort Skiing/Snowboarding" (id 172). Maybe that is what is happening for you? Since there is no separate activity for Snowboard in Garmin Connect it must be logged as "Resort Skiing/Snowboarding".
A fun thing is when the activities are synced to Strava they are logged as "Alpine Ski" and "Snowboard" since Strava got those activity types.
